| (54) | Card payment transaction terminal and card payment transaction system |
| (57) Provided is a system which can prevent a forged card from being used and can find
a person who has done an illegal act of installing a skimmer, by using transmission
information sent from a card payment transaction terminal. When the opening of the
terminal body has been detected, the card payment transaction terminal stores information
of an illegal act that has been performed in a memory, and transmits transmission
information including that information to an external computer. When the external
computer has received card information from the card payment transaction terminal
after having stored the received transmission information in a transmission information
table, the external computer stores the card information in a handled card information
table in relation to the stored transmission information. Further, in a case where
the external computer has received an inquiry about card payment transaction information
including the card information same as a stored handled card information, an inquired
card payment transaction is permitted when the number of times of the inquiry is equal
to or less than a preset number of times, and the inquired card payment transaction
is rejected when the number of times of the inquiry exceeds the preset number of times. |
